Question Simplify the expression 4n2−24n+36 Evaluate (2n−6)2Use (a−b)2=a2−2ab+b2 to expand the expression (2n)2−2×2n×6+62Solution 4n2−24n+36 Show Solution Factor the expression 4(n−3)2 Evaluate (2n−6)2Evaluate 4n2−24n+36Solution 4(n−3)2 Show Solution Find the roots n=3 Evaluate (2n−6)2To find the roots of the expression,set the expression equal to 0 (2n−6)2=0The only way a power can be 0 is when the base equals 0 2n−6=0Move the constant to the right-hand side and change its sign 2n=0+6Removing 0 doesn't change the value,so remove it from the expression 2n=6Divide both sides 22n=26Divide the numbers n=26Solution More Steps Evaluate 26Reduce the numbers 13Calculate 3 n=3 Show Solution
